Caution
*The instruction manual is in English.
*Delivery may be delayed due to importing.
*KB pistons can be installed tighter than other pistons. This results in less piston rock and better ring seal. Please read instructions included with piston for correct piston clearance.
*Due to the thermal conductivity and design of KB pistons, special attention is required to the top ring end gap. Please read instructions furnished with piston for correct ring installation.
*Each replacement ring PART # denotes rings for two pistons, except 84-99 Big Bore kits and 99-06 88 "Twin Cam kits, which require two sets.
